Data-Driven Modelling of a Pelleting Process and Prediction of Pellet Physical Properties

Joseph Emerson, Vincenzino Vivacqua, Hugh Stitt
2021 Johnson Matthey Technology Review  
In the manufacture of pelleted catalyst products, controlling physical properties of the pellets and limiting their variability is of critical importance.  ...  Pellet hardness proved more difficult to predict accurately, with an R2 of 0.67 in 10-fold cross-validation, and 0.63 in an independent hold-out test.  ...  In contrast, purely data-driven approaches are very fast to develop and deploy and are easily adapted to new contexts.  ...

Reconciling Observed Tariffs and the Median Voter Model

Swati Dhingra
2014 Economics & Politics  
Testing the tariff prediction with cross-section and panel data from the 1990s, I show the median voter component is negative in labor-abundant countries and positive in capital-abundant countries.  ...  Negative tariffs are rare, and this paper reconciles the median voter theory with observed protectionism across countries.  ...  In line with the median voter theory of trade policy, I find a negative median voter component in tariffs of countries with scarce human capital and a positive median voter component in tariffs of countries  ...
